Abstract: A crystalline propylene polymer is a homopolymer or a copolymer with a minor proportion of another a-olefin of up to 20 C atoms, an unsaturated carboxylic acid or anhydride or styrene; and has a MFR of 0,1-200 g/1 min so to be moldable; propylene homopolymer or a random copolymer with up to 8% ethylene and optionally also up to 25% butene are preferred. 
     100 parts by wt of polymer, preferably as a nearspherical (as defined) powder of diameter 50-3000 microns, and 0,01-3 parts of a silicone resin having an organic group bonded to Si and rendered non-meltable by heat-curing, as a powder of mean diameter 0,5-7µ, preferably also nearly spherical; and optionally other additives for polyolefins, are mixed, and the polymer is melted, to form pellets which are extruded to make a film which is useful for making packaging. 
     The addition of the silicone improves the antiblocking and slipperiness of the film whilst keeping good transparency and appearance.

Abstract: Friedel Crafts preparation of arylene ether (especially arylene ether ketone) oligomers with an exceptionally high degree of isomeric purity and freedom from by-products can be achieved by adding to the Lewis acid reaction system a protic controlling agent selected from ROX, water, RCOOX, RSO₃X, and ROY, wherein R is organic, X is hydrogen or metal, and Y is metal. 
     Contrary to conventional expectation, the protic agent does not significantly acylate or alkylate the Friedel Crafts reaction product, and controlling agents of relatively low molecular weight, e.g., benzoic acid, can surprisingly be selected to produce dispersions of the resulting oligomers.

Abstract: The invention relates to an optical backscattering measuring instrument with an optical transmitter whose transmitting power is modulated (wobbled) via an oscillator of variable frequency and whose transmitter beam is guided via a beam splitter into an optical fibre, and with an optical receiver which is constructed as a photodiode and to which components of the transmitter beam backscattered from the optical fibre via the beam splitter are fed and in which a mixed signal consisting of a signal proportional to the optical backscattering power and a modulation voltage at the oscillator frequency is formed and evaluated in order to determine the backscattering location and the backscattering intensity. The outlay for the optical receiver is reduced when the photodiode is an avalanche photodiode (4) whose bias voltage is a d.c. voltage (UG) modulated by the modulation voltage (UM), and the mixed signal (Uf) is tapped at a parallel circuit connected in the excitation current circuit of the photodiode (4) and consisting of an ohmic resistor Rp and a capacitor Cp.

Abstract: The present invention relates to a novel biocontrol protein which is a crystal toxin and an insecticide and which is produced in a strain of bacteria genetically altered upon incorporation of a specific gene inserted as a stable gene construction. In particular, the present invention relates to the insertion of the δ-endotoxin gene from B. thuringiensis var. tenebrionis into a cloning vector containing prokaryotic regulatory and replication systems and the utilization of this vector to transform bacterial strains into coleopteran pathogens. Limited deletion of the coding region of the gene of this invention still allows preservation of the insecticidal activity in the protein expressed. In addition, this invention provides genetically altered bacterial strains that are insect toxic and that can be used as a novel method of biological control of agricultural insect pests.

Abstract: A method and system are disclosed for locally introducing fluid, such as a gas, at a predetermined location into molten resin downstream from a resin injection aperture to form a hollow part. The gas is utilized at the localized area to distribute the molten resin, to eliminated molded in stress and to prevent formation of sink marks in the part during resin solidification. An overflow reservoir (112) outside of the mold cavity (114) is filled with the resin during resin injection and then the gas is introduced into the reservoir (112) through a fluid aperture (116, 118) and into the part. The reservoir creates a cocoon of solidified material to act as a seal to prevent gas leakage. One hollow body formed by the method and system includes a substantially endless hollow body portion with a fluid opening for communicating the interior of the hollow body portion with the locally introduced fluid. The hollow body provides an internal gas manifold and means for greater struc­tural integrity.
